The Applications & Gaming Tab - Single Port Forwarding

When you click the Applications & Gaming tab, you will see the

Single Port Forwarding

screen. You can customize

port services for common applications on this screen.

When users send these types of requests to your network via the Internet, the Router will forward those requests

to the appropriate servers (computers). Before using forwarding, you should assign static IP addresses to the

designated servers (use the DHCP Reservation feature on the

Basic Setup

screen).

Single Port Forwarding

Common applications are available for the first five entries. Select the appropriate application. Then enter the IP

address of the server that should receive these requests. Click the

Enabled

checkbox to activate this entry.

For additional applications, complete the following fields:

Application Name

. Enter the name of the application.

External Port

. Enter the external port number used by the server or Internet application. Check with the Internet

application documentation for more information.

Internal Port

application documentation for more information.

Protocol

. Select the protocol

TCP

or

UDP

, or select

Both

.

To IP Address

. Enter the IP address of the server that should receive the requests. To find the IP address, go to

“Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter.” If you assigned a static IP

address to the server, then you can click the

DHCP Reservation

button on the

Basic Setup

screen to look up its

static IP address.

Enabled

. Click the

Enabled

checkbox to enable the applications you have defined. This is disabled (unchecked)

by default.

When you have finished making changes to this screen, click the

The Applications & Gaming Tab - Port Range Forwarding

Wireless-N Broadband Router

The Applications & Gaming Tab - Port Range Forwarding

Port range forwarding sets up public services on your network, such as web servers, ftp servers, e-mail servers,

or other specialized Internet applications. (Specialized Internet applications are any applications that use Internet

access to perform functions such as videoconferencing or online gaming. Some Internet applications may not

require any forwarding.)

When users send these types of requests to your network via the Internet, the Router will forward those requests

to the appropriate servers (computers). Before using forwarding, you should assign static IP addresses to the

designated servers (use the DHCP Reservation feature on the

Basic Setup

screen).

If you need to forward all ports to one PC, click the

DMZ

tab.

Port Range Forwarding

To add an application, complete the following fields:

Application Name

, or select

Both

.

To IP Address

. Enter the IP address of the server that you want the Internet users to be able to access. To find

the IP address, go to “Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter.” If you

assigned a static IP address to the server, then you can click the

DHCP Reservation

button on the

Basic Setup

screen to look up its static IP address.

Enabled

. Click the

Enabled

checkbox to enable the applications you have defined. This is disabled (unchecked)

by default.
